Sure they do. It’s on mobile. While MS isn’t going anywhere in the Enterprise, anyone who is focused on the desktop when it comes to MS development instead of web, cloud, or even cross platform mobile development is headed down a dead end.
If we want to be pedantic, a desktop could be considered mobile too since you can pick it up.
But in the real world when people talk about “mobile software” everyone knows that people are talking about iOS and Android. No one is chasing after the Windows software market, it’s been a diminishing platform for the past decade.
In the real world people are working on laptops, while using iOS and Android mostly to consume content, play games, browse web and show plane tickets.
When they actually become a match to laptops and 2-1 convertibles, maybe.
And there Chromebooks are no where to be seen outside US school system, iPad Pros are mostly a gimmick in rich countries and Android 2-1 are basically phone apps with keyboard.
I am not saying that people aren’t using desktops to do work. What I’m saying that relatively few companies are putting money into writing desktop software. The jobs are limited compared to writing web based software.
If I ever got back into desktop software, it would be highly specialized low level C/C++ code and not WPF/Sharepoint/UWP software.
Which is also a reason why they hardly have a meaningful market share across the enterprise world.
